xiaozhi-esp32-server is a backend service for ESP32 device control that implements the xiaozhi communication protocol using Python, Java, and Vue.
The project provides server infrastructure for the xiaozhi-esp32 open-source hardware platform, enabling ESP32 devices to communicate and be controlled remotely. It implements support for MQTT and UDP protocols alongside WebSocket connections, integrates MCP endpoints for extensibility, and includes voice recognition and knowledge base capabilities. The service follows a human-machine symbiosis intelligence framework developed at the university level.
This tool is designed for users who have already purchased xiaozhi-esp32 hardware and have successfully connected to an existing deployment, but now want to run their own independent backend server. It suits projects requiring local control infrastructure for ESP32 devices with advanced features like voice authentication and knowledge management. The project explicitly targets users with existing hardware investment who need self-hosted deployment rather than relying on third-party services.
The project maintains documentation in multiple languages and provides deployment guides alongside a FAQ section. Development activity includes regular updates with release notes published, and the codebase accepts community feedback through issue tracking. The tool is distributed under an open-source license and includes Docker support for simplified deployment.
